There are a few ballistics programs out there that will graph the path for you. Remington Shoot is, or used to be, free and will give you a general idea where to zero your scope for optimal point blank range for whatever you are shooting at based on your sight above bore height.

My uncle and I argued on this for a while because my dad has a 760 Carbine in 30-06 and for white tail it should be 1" high at 100 yards because he has a low profile flip off mount on his scope. My uncle said he set his 1" high at 100 yards and it was way off at 200 but he has his on a set which allows him to see the iron sights through openings under the scope. He should not be at 1" high at 100 yards because his height above bore is an inch higher making his bullet another inch higher above the bore at 100 yards than dad's.

In other words, dads rifle places the bullet 2.5" above the bore at 100 yards by hitting 1" above the point of aim and my uncles rifle hits 2.5" above the bore by hitting dead on the point of aim at 100 yards.
